Question 1 of 5
A fat soluble vitamin that is essential for the normal hepatic biosynthesis of factors required for blood clotting
Correct Answer: D
Rationale: Vitamin K is a fat-soluble vitamin that is essential for the normal hepatic biosynthesis of factors required for blood clotting. These clotting factors are important for the process of blood coagulation, preventing excessive bleeding when we get injured. Vitamin K plays a crucial role in maintaining proper blood clotting function and a deficiency in this vitamin can lead to increased bleeding tendency.
Question 2 of 5
The following are potential treatments for malignant hyperthermia:
Correct Answer: A
Rationale: Dantrolene is the drug of choice for malignant hyperthermia, as it reduces calcium release from the sarcoplasmic reticulum.
Question 3 of 5
ACE Inhibitors are used in the treatment of all EXCEPT:
Correct Answer: C
Rationale: ACE Inhibitors are primarily used in the treatment of hypertension (Choice A), heart failure (Choice B), and diabetic nephropathy (Choice D). They are not typically used in the treatment of hypotension. In fact, ACE inhibitors can lower blood pressure, so using them in individuals with hypotension may further decrease blood pressure and worsen the condition. Therefore, ACE Inhibitors are not used in the treatment of hypotension.
Question 4 of 5
ACE inhibitors:
Correct Answer: D
Rationale: ACE inhibitors increase bradykinin by blocking its breakdown, not decrease it, so that's false. Hyperkalemia is more common in diabetes due to renal issues, not less, making that false. They're not absolutely contraindicated with NSAIDs, though caution applies, so that's incorrect. They decrease efferent arteriolar resistance, reducing glomerular pressure, a true statement, key in renoprotection. They don't reduce prostaglandins (NSAIDs do). This hemodynamic effect is vital in hypertension and diabetic nephropathy.
Question 5 of 5
A patient with extremely high blood pressure (BP) is in the emergency department. The physician will order therapy with nitroglycerin to manage the patient™s BP. Which form of nitroglycerin is most appropriate?
Correct Answer: D
Rationale: In a patient with extremely high blood pressure requiring immediate treatment in the emergency department, the most appropriate form of nitroglycerin is the intravenous (IV) infusion. IV nitroglycerin allows for rapid onset of action, precise control of the dosage, and continuous monitoring of blood pressure to achieve the desired therapeutic effect. In this critical situation, the sublingual spray, transdermal patch, and oral capsule forms would not provide the rapid and precise control needed to manage the patient's high blood pressure effectively. IV nitroglycerin is the preferred route of administration for patients with hypertensive emergencies.
